Certain exemplary embodiments can provide a wall frame comprising a top plate, a bottom plate, a first end column, a second end column, a plurality of studs, and a plurality of purlins. Each of the plurality of purlins is an edge of a pair of cells, the pair of cells having edges comprising three edges that comprise one or more of a part of the top plate, a part of the bottom plate, a part of the first end column, a part of the second end column, a part of the plurality of studs, and another of the plurality of purlins.

A bracket for reinforcing a wooden joist provided with a hole for the passage of a utility conduit. The bracket includes a base wall having a central opening, sized to accommodate the utility conduit, for positioning against one side of the wooden joist. A pair of integral side walls extend at right angles from the base wall. A pair of integral flanges extend at right angles from the pair of side walls so as to be parallel to the base wall.

An interactive computer graphics display system processing method for identifying a displayed primitive that intersects an operator selected area of the display screen. Pursuant to the method, the operator selected area of the display screen is reverse mapped to world coordinate space; data representative of displayed geometric primitives is then clipped against the reverse mapped selected area in world coordinate space; and clipped data representative of displayed geometric primitives that intersect the reverse mapped selected area are identified for operator defined application processing. Further processing steps include mapping of the identified data to screen coordinate space and rasterization of the data for display in the screen monitor. A zoom processing method is also provided wherein an original operator defined zoom window is transformed from screen coordinate space to world coordinate space and the boundaries of the transformed window in world coordinate space are utilized as data clipping boundaries. After clipping, data representative of a displayed geometric primitive outside the inverse mapped zoom window is discarded, thus preventing the rerasterization of geometric primitives outside the zoom window. Further processing includes mapping of the identified data to a defined zoom window in screen coordinate space for operator viewing and selection of a particular geometric primitive for application processing.

Certain exemplary embodiments can provide a two piece bracket constructed to reinforce a wooden joist. The wooden joist defines a central aperture. The central aperture is constructed to substantially surround a portion of a utility conduit passing therethrough. The two piece bracket is constructed to be positioned against one side of the wooden joist. The two piece bracket comprises a first piece and a second piece.

Certain exemplary embodiments can provide deck bracket, which comprises a bracket face. The bracket face is substantially planar and defines a first plane. The deck bracket comprises a first bracket wall and a second bracket wall, each of which directly contact the bracket face. The deck bracket comprises a first bracket flange that directly contacts the first bracket wall and a second bracket flange that directly contacts the second bracket wall.

A method for clipping two and three dimensional graphic primitives for use in a computer graphics workstation. During the first clipping stage, the system removes all graphic primitives which lie outside an arbitrary clipping volume or window that is an enlargement of the desired viewing volume or window. This clipping volume (window) is then projected and mapped onto a virtual viewport which is larger than the real viewport. After this mapping occurs, rendering effects (such as line styles, line width, pattern fill, hatch fill, etc.) are applied to the primitive. A subsequent stage of clipping is then applied to clip the virtual viewport to the real viewport which is the user's visible area. Use of the clipping volume (window) during the first stage of clipping makes it simpler to transform geometric primitives which are partially visible to the viewer, and gives visible primitives a richer set of invariant geometric properties so that their rendering effects may be more easily and correctly carried out.
